Jen exercises 30 minutes each day on monday, wednesday, and friday. she practices yoga for 45 minute on tuesday. how many hours per week does jen spend exercising and practicing yoga?

2 1/4 hours or 2.25 hours or 9/4 hours. This depends on your choices.

Step-by-step explanation:

Exercises

30 minutes = 1/2 hour

3* 1/2 = 3/2 hours

Yoga

45 minutes = 45 minutes / 60 minutes//hour = 3/4 hour

Total

3/2 + 3/4 = 6/4 + 3/4 = 9/4

9/4 = 2 1/4 hours.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
